The International Journal of Advanced Manufacturing Technology, 2015
This paper carries out a finite element (FE) analysis to investigate the effects of grinding speed (20∼400 m/s) and undeformed chip thickness (1∼8 μm) on chip formation dur- ing single grain grinding of nickel-based superalloy Inconel 718. Three factors related to the Johnson-Cook (J-C) consti- tutive model, i.e., the strain hardening, strain-rate ...

Many important and complex parts, such as aero-engine compressors and automotive punch dies, are often machined in five-axis computer numerically controlled (CNC) milling. To machine the parts with accurate dimensions and shapes and low machining costs it is necessary to construct 3D models of the finished parts in the geometric simulation and in ...

International Journal of Modern Physics B, 2006
In this study, effects of the maximum undeformed chip thickness on roughness of ground surface and specific grinding energy were investigated. The acoustic emission (AE) signals generated during grinding processes have been analyzed to find out the appropriate AE parameters for assessing the processes.

Abstract The precise modeling of the instantaneous undeformed chip thickness is one of the key issues in the mechanics of micromilling. While most current models noticed the influences of the tool tip trochoidal trajectory and tool runout, they took account only the workpiece removed by immediate passing tooth but not more preceded teeth.

Aim. The aim of this paper is to create a 3D model of the undeformed chips produced during the cutting of an internal gear ring. By modelling the power skiving process, it is necessary to investigate the influence of various geometric and technological parameters on the thickness and cut area of the chips produced. Method.

Model of the instantaneous undeformed chip thickness in micro-milling based on tooth trajectory
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2016Instantaneous undeformed chip thickness is one of the key parameters in modeling of micro-milling process. Most of the existing instantaneous undeformed chip thickness models in meso-scale cutting process are based on the trochoidal trajectory of the cutting edge, which neglect the influences of cutter installation errors, cutter-holder manufacturing ...

Critical undeformed chip thickness of brittle materials in single point diamond turning
The International Journal of Advanced Manufacturing Technology, 2015In this work, the ultimate compression force that enables the plastic removal of brittle materials in diamond turning is initially modeled according to the theory of rigid-plastic mechanics. And subsequently, an independent oscillator model is reconstructed to calculate the microfriction force that appears at contact interface.
